The utility model discloses a cylinder head rocking arm axle dismounting device, reach the dismantlement subassembly of being connected with positioning supporting plate (4) clearance fit including pneumatic wrench, positioning supporting plate (4). Dismantle the subassembly include screw (1) that outwards sets gradually from the lining, screw rod (2) and with screw rod (2) threaded connection's screw sleeve (3), screw rod (2) inner chamber is the interior through -hole with screw (1) external diameter looks adaptation. Bilateral symmetry is equipped with and installs tang hole corresponding positioning connecting hole (5) and supply 1 screw through -hole (6) corresponding with rocking arm axle screw hole that pass on the screw with cylinder head side cap face on positioning supporting plate (4). This device structural design is reasonable simply, low cost, and it is convenient, easy to dismantle, and labour saving and time saving and province are artifical, ensures cylinder head rocking arm axle and dismantles quality and safety, improves and reprocesses efficiency, practices thrift repair cost, has increased substantially cylinder head rocking arm axle dismantlement efficiency.
Description
Technical field
This utility model relates to technical field of engines, is specifically related to a kind of cylinder head rocker arm shaft provision for disengagement.
Background technology
Engine cylinder head rocker arm shaft is connected with cylinder head rocker shaft hole, is essentially all employing interference fit and connects, adopts when rocker arm shaft assembles hammer or impact gun to squeeze into.When certain parts of cylinder head occur that quality problems or abrasion need to change, such as inlet and exhaust valve gas leakage, the situations such as camshaft or rocking arm inordinate wear need rocker arm shaft is dismantled when occurring, prior art is to take a double threaded screw, screw rod one end is screwed in rocker shaft hole, the other end penetrates in the circular iron block hole of certain mass, nut is screwed in again in screw tip, by using impulse inertia that circular iron block slides on screw rod to be extracted from hole by rocker arm shaft, need two people to coordinate just can complete, one people pins cylinder head, circular iron block is carried out sliding and impacts by one people.Often one rocker arm shaft of dismounting typically requires and could be extracted by rocker arm shaft through repeat impact, usually flies out due to the inertia of slide block when rocker arm shaft is extracted simultaneously, and slide block is likely to hit people and thing, produces potential safety hazard.This provision for disengagement, not only time-consuming, effort and dangerous, production efficiency is also low.
Utility model content
The purpose of this utility model is to overcome the deficiency in existing provision for disengagement technology, " a kind of cylinder head rocker arm shaft provision for disengagement " is provided, this apparatus structure is reasonable in design simple, with low cost, convenient disassembly, easily, time saving and energy saving and less manpower, it is ensured that cylinder head rocking arm dismounting hinge pin quality and safety, improves and reprocesses efficiency, cost is reprocessed in saving, and cylinder head rocker arm shaft removal efficiency is greatly improved.
To achieve these goals, this utility model is achieved through the following technical solutions: a kind of cylinder head rocker arm shaft provision for disengagement, and main technical scheme is, including pneumatic impact spanner, locating support plate 4 and the dismounting assembly that is connected with locating support plate 4 matched in clearance.
Screw 1 that described dismounting assembly includes setting gradually inside-out, screw rod 2 and the screw sleeve 3 threadeded with screw rod 2, described screw rod 2 inner chamber is the inner via hole suitable with screw 1 external diameter.
Further technical scheme is, on locating support plate 4, left and right is arranged with and installs be located by connecting hole 5 and the screwing through hole 6 corresponding with rocker arm shaft screwed hole for screw 1 traverse that seam hole is corresponding with cylinder head side cover face.
Further technical scheme is, the lower end of described screw 1 is provided with the external thread section 7 suitable with rocker shaft hole female thread.
This utility model has the advantage that
This apparatus structure is reasonable in design simple, with low cost, convenient disassembly, easily, and time saving and energy saving and less manpower, it is ensured that cylinder head rocker arm shaft dismounting quality and safety improves and reprocesses efficiency, saves and reprocess cost, cylinder head rocker arm shaft removal efficiency is greatly improved.
Accompanying drawing explanation
Fig. 1 is that assembling of the present utility model is main looks sectional structure schematic diagram.
In figure, 1, screw 2, screw rod 3, screw sleeve 4, supporting block for location, 5, be located by connecting hole, 6, screwing through hole, 7, external thread section.
Detailed description of the invention
Below by non-limiting example, this utility model is expanded on further, understands this utility model.
Embodiment
As it is shown in figure 1, a kind of cylinder head rocker arm shaft provision for disengagement, including pneumatic impact spanner, locating support plate 4 and the dismounting assembly that is connected with locating support plate 4 matched in clearance.
Screw 1 that described dismounting assembly includes setting gradually inside-out, screw rod 2 and the screw sleeve 3 threadeded with screw rod 2, described screw rod 2 inner chamber is the inner via hole suitable with screw 1 external diameter.
On locating support plate 4, left and right is arranged with and installs be located by connecting hole 5 and the screwing through hole 6 corresponding with rocker-arm roller pin male thread hole for screw 1 traverse that seam hole is corresponding with cylinder head side cover face.
The lower end of described screw 1 is provided with the external thread section 7 suitable with rocker shaft hole female thread.
Concrete disassembling section method:
1, first the locating support plate 4 of provision for disengagement is arranged on cylinder head side cover face to be located by connecting on hole 5, and screwing through hole 6 is directed at rocker shaft hole；
2, screw sleeve 3 and screw rod 2 screwed assembly are arranged on the screwing through hole 6 on locating support plate 4；
3, through screw rod 2 inner via hole and screwing in rocker shaft hole by screw 1, operator's left-handed screw sleeve 3, right hand pneumatic impact spanner is inserted in the reversion of screw rod 2 turret head and produces reverse torque and extracted by rocker arm shaft.
In sum, this utility model reasonable in design is simple, with low cost, convenient disassembly, easily, time saving and energy saving and less manpower, it is ensured that cylinder head rocker arm shaft dismounting quality and safety, improves and reprocesses efficiency, cost is reprocessed in saving, and cylinder head rocker arm shaft removal efficiency is greatly improved.
